Answer
the anser is (C) as 240 Watt
Explanation
As we know that
[tex]Power= Work/Time[/tex]
[tex]Work = Force * Distance[/tex]
As given in question
Force = 150 N
Distance = 4m
Then work is
[tex]Work = 150 * 4 Nm[/tex]
[tex]Work = 600 Nm[/tex]
[tex]Power= 600/2.5[/tex]
[tex]Power= 240 Watt[/tex]
So the answer is 240 watt
